HANGER FOR- TROLLEY WIRES AND THE LIKE.

Application filed June 9, 1924. Serial No. 718,9 70.

ToaZZ whom it may concern: I I

Be it known that I, -WINroRD GLADSTONE MILNE, a subject of the King ofGreat Britain, and a resident of the city of I-Iam'lton, county ofBIIUVOItlI, Province of Ontario, Dominion ofCanada, have inventedcertain new and useful Improvements in Hangers for Trolley Wires and thelike, for which thefollowing is the specification.

My invention relates to improvements in hangers for trolley wires andthe like, such for instance as catenary hangers and the object of theinvention is to provide a stronger and more durable and reliable hangerthan hitherto, and whichwill be of simple and inexpensive construction.

lWIy invention consists of a wire gripping ear and a novel form of earsupport associated therewith, all as hereinafter more particularlydescribed and illustrated in the accompanying drawings in which Fig. 1is a side elevation of my invention.

F g. 2 is an end elevation of Fig. 1 looking in the direction of anarrow.

Fig. 3 is a section on the line 33 of Fig. 2.

In the drawings, like characters of refercnce indicate correspondingparts in the various views.

My invention conssts of a wire gripping car 1 and an ear support 2.

The ear 1 comprises the opposed side plates 3, which are separated attheir upper edges by a spacing element 4.

The lower edges of the plates 3 are formed into the opposed wiregripping jaws 5 adapted to engage and grip the wire 6 therebetween.

The top of the ear 1 is provided with an orifice 7 therethrough, thepurpose of which will hereinafter appear.

A bolt 8 extends transversely through the ear 1 intermediately thereofand carries a nut 9.

The ear support 2 is formed from a rod having its lower end bent backupon itself to form an eye 10, this backwardly bent end of the rodprojecting upwardly and the extremity thereof formed into a hookedportion 11, which projects upwardly through the orifice 7.

The construct'on and operation of my invention is as follows The lowerend of the ear support 2 is bent back upon itself as shown in thedrawings. V

The eye ,10 is. then passed inwardly through the orifice 7 in the top oftheear and the bolt 8 passed through the e'arand through the eye 10.

Upon tightening the nut 9, the sides ofthejear are drawn inwardly andthe wire 6 1s firmly grippedbetween the jaws 5.

In this assembled posit on the hooked por tion 11 projects upwardlythrough the ori Hitherto considerable troublelias been ex; perienced introlley wire hangers of this type due to the ear support pulling awayfrom the ear and it has been with a View of overcoming this that I havedevised my. invention.

When the trolley wire becomes displaced out of its normal line, the earsupport 1 is subjected to very severe bending strain,

vention by having the free end 11 of the rod 2 project back upwardlythrough the orifice .7 in the car, after the rod has been bent about thebolt 8 to form the eye 10. In this way the engagement of the twoportions of the rod 2 (that is the main body of the rod and the end 11)Within the orifice 7, positively prevents the straightenng out of theeye 10 and the consequent disengagement of the ear support- 2 from the'ear 1.

The hooked portion 11 is bent outwardly sothat it will engage the top oftheear inimediately any straightening out deformation of the support 2takes place. i

It has been found by actual test that when the ear support 2 is formedfrom quarter inch rod, this red will break before the end 11 willstraighten out over the bolt 8.

Various modifications may be made in my invention without departing fromthe spirit thereof or the scope of the claims and therefore the exactform shown is to be taken as illustrative only and not in alimitingsense.

From the foregoing it will be apparent that I have devised improvementsin devices of the class mentioned, which should prove of great value.

lVhat I claim as my invention is:

1. In a device of the class described, the combination with an ear,comprising opposed wire gripping jaws and a bolt mounted in the ear andoperatively coacting with the jaws, of an ear support comprising a rodextending downwardly and bent backwardly upon itself about the aforesaidbolt, and means formed on the ear and coacting with the backwardly bentportion of the rod.

, for preventing the straightening out of said bent portion.

2. In a device of the class describech, the combination with a wiregripping ear comprising opposed spaced apart side plates separated attheir top edges by a spacing element and adapted to grip a wire betweentheir lower edges, and a boltextending through said platesintermediately thereof,

of an ear support comprising a rod extend ing downwardly between saidopposed side plates through an orifice in the top of the ear, the end ofsaid rod bent baokwardly upon itself about the aforesaid bolt andprojecting upwardly through the orificein the top of the ear.

3. In a device of the class described, the combination with a wiregripping ear comprising opposed spaced apart side plates separated attheir top edges by a spacing element and adapted to grip a wire betweentheir lower edges, and a bolt extending through said platesintermediately thereof, of an ear support comprising a rod extendingdownwardly between said opposed side plates through an orifice in thetop of the ear the end of said rod bent backwardly upon itself about theaforesaid bolt and projecting upwardly through the orifice in the top ofthe ear, the extremity of said rod bent to form a hooked portion adaptedto engage the top of the ear.

4. In a device of the class described, the

combination with an ear comprising opposed
